BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 586,980, dated July 2'?, 1897. Application filed September 8, 1896. Serial No. 605,068. (No model.)

p a specification.

My invention relates to improvements in.

bottle-Stoppers; and the object of the invention is to design asimple and cheap form of bottle-stopper which will effectually and securely close the bottle and in which none of the parts of the stopper that Will injuriously aifect the contents are exposed to the contents or interior of the bottle; and it consists, essentially, of a suitable stem provided with a suitable plug, preferably of Wood, having an upper flange, a sleeve of rubber designed to fit around the plug and abut the upper flange, a disk of felt fitted beneath the plug, and a retaining nut or disk which is secured on the threaded end of the stem, so as to hold the felt disk in position,fas hereinafter more particularly explained.

Figure 1 is a sectional perspective view of a bottle and stopper made in accordance with my invention. Fig. 2 is a perspective detail of the stopper complete. Fig. 3 is a perspective view of alternative form of stopper. Fig. is asectional view of the alternative form shown in Fig; 3.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the bottle, in which the stopper is intended to fit and close from within. The stopper is made in ve portions, consisting vof the stem B, provided with a threaded lower end b, the top disk O, secured thereto, the

plug D, fitted onto the stem and provided with an upper flange d, the rubber sleeve E, fitting Onto the plug and designed to abut the flange at the top thereof, the felt disk F, fitted beneath vthe plug, and the disk-nut G, fitted beneath the felt disk. The disk O may be made of metal. The plugD is preferably made of wood or other suitable cheap material having like properties. The sleeve E is made preferably of rubber on account of its elastic and compressible qualities, the outer periphery of the' sleeve being preferably, when the stopper is down, as shown in dotted lines in Fig. l, of greater diameter than the interior of the neck of the bottle.

The felt disk F is preferably treated with a suitable chemical, so as to give it non-absorbent qualities. The nut-disk G is made of porcelain or any other suitable material of like quality and is preferably of less diameter than the sleeve and is also preferablybeveled, as shown.

It will be seen in the construction of stopper that both rubber and metal are entirely separated from the interior of the bottle when the stopper is thrown up into the neck, as shown, as the felt bends down and closely fits the lower portion of the neck. This noneXposure obviates the defect heretofore so commonly incident in Stoppers-that is to say, the contact of the fumes or liquid with the rubber and metal, which so detrimentally affect the contents of the bottle.

By the construction of stopper which I describe there is no reason why the contents of the bottle will not always remain perfectly sweet and pure.

In Fig. 4 I show the sleeve D' as made cnt-irely of rubber instead of providing a wooden plug and an outer sleeve, as shown in Fig. 1, but I prefer the form shown in this latter figure, as it is much cheaper 'and more effective.

Vhat I claim` as my invention isl. In a bottle-stopper the combination with a vsuitable stein, of a rubber sleeve connected thereto, a non-absorbent felt disk situated beneath the sleeve and a non-corrosible disknut secured on the stem beneath the sleeve vand covering the end of such stem as and for the purpose specified.

2. In a bottle-stopper the combination with a suitable stem, of a wooden plug connected thereto provided with an upper flange, a rubber sleeve fitting the interior of the plug, a non-absorbent felt disk situated beneath the sleeve and plug and a non-corrosible disk-nut secured on `the stein beneath the sleeveand ICO sleeve and arranged below the same on said 1o stem, and the rigid disk below said flexible disk, whereby the neel; of the bottle below said sleeve is sealed when said stopper is in place, substantially as described.
